+Package clienttiming gives an HTTP client for go-server-timing middleware.
 
-An HTTP client for [go-server-timing](https://github.com/mitchellh/go-server-timing) middleware.
+It provides:
 
-## Features:
+An HTTP `Client` or `RoundTripper`, fully compatible with Go's standard library.
+Automatically time HTTP requests sent from an HTTP handler.
+Collects all timing headers from upstream servers.
+Customize timing headers according to the request, response and error of the HTTP round trip.
 
-* An HTTP `Client` or `RoundTripper`, fully compatible with Go's standard library.
-* Automatically time HTTP requests sent from an HTTP handler.
-* Collects all timing headers from upstream servers.
-* Customize timing headers according to the request, response and error of the HTTP round trip.
+## Sub Packages
 
-## Install
+* [example](./example)
 
-`go get -u github.com/posener/client-timing`
 
-## Usage
+---
 
-1. Add a `*clienttiming.Timer` to your server handler, or create it in the handler function itself.
-2. Wrap the `http.Handler` with [`servertiming.Middleware`](https://godoc.org/github.com/mitchellh/go-server-timing#Middleware).
-2. In the handler function, having `timer` of type `*clienttiming.Timer` and `req` is the `*http.Request`:
-
-    a. Create an [`*http.Client`](https://godoc.org/net/http#Client) using `timer.Client(req.Context())`
-
-    b. Or create an [`http.RoundTripper`](https://godoc.org/net/http#RoundTripper) using `timer.Transport(req.Context())`
-
-3. Use option a or b directly or inject it to a library that accepts them, in your outgoing HTTP request
-   from the handler.
-4. That is it! the timing header will appear in the response from the handler.
-
-## Example
-
-Suppose we have an HTTP handler:
-
-```go
-type handler struct {
-	timer *clienttiming.Timer
-}
-```
-
-Our usage of that handler will be:
-
-```go
-func main() {
-	h := &handler{
-		timer: clienttiming.New(clienttiming.WithName("my-server")),
-	}
-	log.Fatal(http.ListenAndServe(":8080", servertiming.Middleware(h)))
-}
-```
-
-
-### Example for `Client` function:
-
-```go
-func (h *handler) ServeHTTP(w http.ResponseWriter, r *http.Request) {
-	// Create an http client using the request context
-	c := h.timer.Client(r.Context())
-
-	// Perform HTTP requests, as many as you like
-	resp, err := c.Get("https://golang.org/")
-
-	...
-}
-```
-
-### Example for `Transport` function:
-
-```go
-func (h *handler) ServeHTTP(w http.ResponseWriter, r *http.Request) {
-	// Instrument an http client with a timing transport
-	c := &http.Client{
-		Transport: h.timer.Transport(r.Context()),
-	}
-
-	// Perform HTTP requests, as many as you like
-	resp, err := c.Get("https://golang.org/")
-
-	...
-}
-```
-
-### Run the [example](./example/main.go)
-
-`go run ./example/main.go`
